Troubleshooting
Switching input/output with the front panel keys are not
responsive.
• Press and hold the key for 2 seconds, then release, instead of
just a quick press.
Loss of video output or color, or the unit becomes unusually
hot.
• If the signal voltage dierence between the video source
device(s) and the matrix switch is too large, hot plugging
could easily cause damage to the IC chips. Please turn o the
power to the system before plugging or unplugging.
The LCD displays normally and the communication port has
a return code but no image is being output.
• The output/input cable connectors are loose. Simply
reconnect the cables.
• The connection cable short-circuited. Simply replace the
cable.
• The connection cable is broken. Simply replace the cable.
The front panel keys and communication ports are not
responsive.
• Check that the equipment input power is properly connected
and the computer communication ports are working.
• Disconnect all cables and power and let sit for several
minutes before attempting to use again.
• Otherwise, contact technical support for further assistance.
